wi-fi dongle problems!

[sundays]

Hello. I have a bush smart tv model LED40127FHDCNTD. I bought this tv last month and was working ok. i did setup the internet connection trough the usb wi-fi provided. Now the tv dont recognize the dongle anymore. when insert saying dongle detected but straight away says dongle removed, when she is still inserted. Can anyone provide some help. do I have the dongle damaged? how to test? Many Thanks

Try another usb port, and if it still fails return the dongle as it sounds defective.
